This week’s theme is how idealism fuels philanthropy. My A Block is about the Bill and Melinda Gates Foundation—the largest in the world; the Big Interview is with Vanessa Tennyson, a transgender woman who transitioned from high level executive to philanthropist/entrepreneur/3:00 a.m. telephone crisis counselor for LGBTQ people; and in my C Block, I share about how I honored my Aunt Margaret with a bit of philanthropy of my own.
